In oura'pplication Serial No. 386,932, led August 3, 1907, we have described and 'claimedtrip actuated mechanism for the.

purpose of automatically controlling the speed of trains. In such mechanism we emp 0y depending trip armscarried by the en 'ne or train and adapted under certain conitionsto engage and be actuated by tri or stop arms located along the track. Iihch engine or train is provided with two or morel of the trip arms situatedv in different vertical planes, :the operation of one of said arms eifecting an emergency application of of trainsinto and out of thethe brakes and the. operation of. the other arms'effecting a service, or. partial, application of the brakes.

Our resent invention has relation-more particu arly to means whereby the passage track sections or blocks will automatic'allymove the track tri sor stops into-and out of engaging positions, the object beingto provide means whereby the mechanism onthe train will be automatically operated to effect an emergen'cy application--ofthe' brakes when the train comes to a home signal set at-st'op position, and toautomatically effect a service application of the brakes when the train comes to a distant si "al set at cautionposition, provided-the speed of the trainat that time exceeds the predetermined limit.

The armature 1" of the relay R contro s the-connections of the magnet of the controller DC with the battery B The armature r of the relay R controls the connection of the magnet of the controller HC with the battery B abo 1s a switch or circuit breaker, which is I actuated bythe movement of the track stop DS to, control the circuit of the magnet DM, said magnet being connected in series and re,- ceiving its current supply from "the battery B'through the armature r of a relay R and through the switches tm: and a'bc'. The switch def is connected to the track'stop HDS, to be actuated-thereby, as is also the switch a'bc.- Zmn, tm; and eye are three switches which are connected to be operated in unison by themovement of. the home signal arm H.

I ing thethree switches signal blades will be in clear positilln, the

circuits ,of the various controllers being closed. The presence of a train in any block, or the failure of any of the parts to work, opens the circuits of the corres ending signals and stops and immediate y puts such signals and stops to stop osition. It being remembered, therefore, tliat the parts are breaking of the circuits of the respective will be easily un- Fig. 1 shows the normal position, with the blocks A, B, C clear and the parts in en a train enters the 1s causes the armature r to fall, thereby opening the circuit of the controller ing the stop arms DS sition. v s movement of the stop arm breaks the circuit of the magnet DM at the point 6 and the signal arm D goes to caution position. The signal arm H does not at this timev o to stop position, owin to the up into operative poarmature r of the relay As soon as the'train passes out of the block A the relay R again picks up but the closing of the circuit of the controller DC- to move the stop arm DS to clear position is not effecteduntil the train asses into the block C, as hereinafter descri ed.

When the train enters the block B, the relay B is short-circuited. This causes the armature 1" to drop and opens the circuit of the controller HC and of the magnet .HM.

The 0 ening of the switch Zmn opens the circuit 0-?- the magnet DM, and the distant si D goes to caution position. The circuit of the magnet Ris also opened, thereby dropping the armature r and o enin cuit of the controller DC, w ich firings the track trip or stop HDS to operative p'osi-' ,The movements of "the track stop HDS also opens the switches def and abc as shown in Fi As the train the block C, the relay R This closes the circuit of the controller H and the trackstop HDS is moved thereby laterally position P on the locomotive.

This causes the home signal arm to o toclea'r in turn closes the circuit of the controller DO, moves the stop HDS out of operative osition, and closes the circuit of the magnet M. The distant signal arm D now clears. While for reasons" before explained, the home signal forthe block A and the distant signal for the block C are not shown, it will be readilyunderstood that in a com lete installation,the track stops 'DS. and S" will each have twocontrollers similar to'those'of the'traok stop HI) S, actuated and controlled a The several controllers. for actuating the track stops, and the signal blades, may be e or of any other suitable variety. It is a sd obvious that various changes may be made and the parts are in workin in the circuit connections [without afiecting our invention.
